I don’t know why, but there are more and more students wearing glasses nowadays. I remember when I was a kid at school, I was very curious if there were one or two students wearing glasses in my class, but now it seems to be the other way around. Today, we are not going to talk about the causes of myopia, but rather focus on how to match a pair of myopic glasses to suit your needs. Now many cities have a lot of eye stores, businesses also have a number of sales strategies to sell glasses, both in price and service, will make people satisfied, so there are many parents take their children there, it is convenient to match a pair. It does not know that the optometry is called optometry in ophthalmology, is a very complex branch of ophthalmology, and can not be mastered overnight, after a very professional learning and training, many medical universities currently have optometry. Therefore, from the medical point of view, prescription glasses should be a more serious medical practice, rather than a simple commercial sales. Generally speaking, you should go to a large general hospital ophthalmology or eye hospital for a detailed eye examination, in addition to exclude other diseases of the eye resulting in poor vision, and then comprehensive optometry, for 14 years of age or younger must be dilated optometry, because many of them suffer from pseudomyopia (regulatory myopia) or myopia, but contains a regulatory component, through the dilated pupil, pseudomyopia will be cured, no need for glasses. No more prescription lenses, true myopia can be tested for an accurate myopia degree. Now there are many businesses that also dilate the pupil (fast pupil dilatation), in order to save time (about half an hour), while in the hospital it takes 3 to 4 days and half a month to recover, but I did not realize that fast pupil dilatation only dilates the pupil, and does not paralyze the ciliary muscle, our goal is to eliminate the ciliary muscle spasm caused by regulatory myopia, fast pupil dilatation has no such effect. This is why it has little effect on the results of optometry. Therefore, to get glasses, especially for children, it is best to go to the hospital for a detailed eye examination or even a dilated eye exam before deciding on glasses.
